Basic and diluted net income per common share
 
The Company’s basic net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding during the period. The Company’s diluted net income per common share is computed by dividing net income by the weighted-average number of common shares outstanding plus any incremental shares arising from the dilutive effect of stock-based compensation.
